Isn't equally as creepy for her to try and recreate a daddy daughter situation
If that's what she's doing, then yes it absolutely is. Just as if you apply it to older woman and younger man, it's every bit as creepy. However I don't think we should apply that to everyone in a relationship involving a notable age difference (defined as 10 years or more difference). For example, I am something like 15 years older than you and were I in a relationship with you I can assure you it would not be because I was trying to create a mother-son type of bond.
